1. A ramp assembly comprising:
- a first layer having at least one first block, each first block having;
a top surface spaced apart form a substantially parallel bottom surface, thereby defining a block thickness;
opposed and substantially parallel first and second walls having a length defining a longitudinal axis;
opposed and substantially parallel first and second ends separated by the length;
the top surface, the bottom surface, the first and second walls and the first and second ends together forming a block body;
the top surface having a projection extending therefrom; and
a second layer having at least one second block, each second block having;
a top surface spaced apart from and inclined relative to a bottom surface, thereby defining a block thickness;
opposed and substantially parallel first and second walls having a length defining a longitudinal axis;
opposed and substantially parallel first and second ends separated by the length;
the top surface, the bottom surface, the first and second walls and the first and second ends together forming a block body;
wherein the bottom surface of the second block has at least one groove adapted to engage the projection of the top surface of the first block, thus forming an interlocking arrangement.

Abstract
In a method for forming a block having a core, the core is formed in a vertical orientation, providing for increased control of wall thickness. The block has a projection on one surface and a groove on an opposing surface. The block core is disposed parallel to the projection and the groove. The block may be used in a step assembly, a ramp assembly, or a wall. Assemblies made from the block are easy to construct and can be assembled with or a without adhesive.
